Abstract: The Authors, after a short description of the morphology and the biology of O. cribricollis, point out for the first time that the species is harmful to carrots on the Lazio coast-line. The damage has affected 20% of its production and has been caused by the larvae excavating blind tunnels. No damage can be ascribed to the adults which have probably reached the carrot crops from other crops. Although the extent of the infestation is limited to the perimeter of the crop, it is worth investigating the abiotic and biotic factors which regulate the dynamics of the O. cribricollis population. This is seen as necessary in order to find rational methods of control.1997-12-31T23:00:00Z
